The development environment used in this course is Visual Studio Community edition (often abbreviated to: VS). VS is a program in the size of about 600 megabytes and you can make games, apps and lot's of different kinds of programs for phones, pc, Xbox etc.. Please note that there could be different (newer) versions of Visual Studio and that they could look a bit different than shown in this course.

With Visual Studio you can create C# source code. This is the programming language in which you give instructions to a computer (=programming) to do what you want it to do (for example if a user clicks a button).

How do you install VS Community?

Open your browser and go to https://www.visualstudio.com/ and choose: "Download for Windows: Visual Studio Community". Only this community version is free. If you work on a Mac system please read this before you go on. Please note that Microsoft updates their websites regularly so it could look a bit different.
Installing the software shouldn't be such a problem but pay attention when you reach the step "Workloads". Choose (at least) ".Net desktop development". All other screens in the installation won't give a problem if you pick the standard choices. In the example below you can see where you can select the ".Net desktop development". Don't forget this!
Select: ".NET desktop development" (on top of the middle column in this picture).

Because of the fact that Microsoft will change Visual Studio regularly and the install process could look different with each new version please take a look at the Microsoft websites for more explanation in how to install Visual Studio Community edition. The most important choice you have to make for using VS with this course can be read above (on this page).
